Abstract: Leaf disks of Vitis vulpina L. were incubated in hquid media containing 0,75,100, 125,150,200 and 225 mmol•L-1 NaCl with or without 1 μmol•L-1 zeatin, at 25 ℃ ,under 1 000 μmol • m-2 • s-1 continuous illumination, leaf relative permeability, contents of photosynthetic pigments and soluble protein, and activities of catalase (CAT), ascorbate peroxidase (AsA-POD) and guaiacol peroxidase(G-POD) were compared. The results showed that relative leaf permeability was increased following the increase of NaC1 concentration, whereas activities of leaf CAT, AsA-POD and G-POD, and contents of leaf photosynthetic pigments were reduced significanfiy. These effects of salt stress were significantly inhibited in the presence of zeatin. The ,relationship between relative leaf permeability and activities of H2O2 scavenging enzymes were discussed.
